In February, tractor exports crossed the one-lakh mark for the year for the first time Why are India’s tractor exports soaring? Which countries are making the most buys?Ĭommerce and industry minister Piyush Goyal tweeted that India’s exports of tractors registered a spectacular growth of 224 per cent in April-July 2022 over the same period in 2013. The relatively high frequency content across shorter time span of demolition vibration ensures that the actual ground displacement is so low as to generally not be problematic How strong an earthquake will Noida twin towers cause when they come down?ĭemolition-induced vibrations are different from earthquakes. The study is published in the journal Royal Society Open Science. The researchers plan to test the thermoregulation hypothesis, either by studying the behaviour of air currents over zebra pelts, or by implanting wild zebras with temperature sensors, if they are granted permission to do so, Larison said. The team found that the plains zebras with the most-defined torso stripes generally lived in the Northern, equatorial region of their range, whereas those with less-defined torso stripes were more common in the Southern, cooler regions of the range - a finding that supports the thermoregulation explanation. Other animals also need to regulate body temperature, or thermoregulate, said study co-author Ren Larison, a researcher in the Department of Ecology and Evolutionary Biology at UCLA, but zebras may especially benefit from an extra cooling system because they digest food much less efficiently than other grazers in Africa.Īs such, zebras need to spend longer periods of time out in the heat of the midday sun, eating more food. These findings suggest that torso stripes may do more to help zebras regulate their body temperature than to avoid predators and tsetse flies, 'Live Science' reported. The scientists found that the definition of stripes along a zebra's back most closely correlated with temperature and precipitation in a zebra's environment, and did not correlate with the prevalence of lions or tsetse flies in the region.

Researchers at the University of California, Los Angeles (UCLA) examined how 29 different environmental variables influence the stripe styles of plains zebras at 16 different sites from south to central Africa.
